IMPROVEMENT IN' ICE-PICKS.

Specification forming part of Letters Patent No. 167,745, datedSeptember 14, 1875; application filed February 23, 1875.

To all whom it may concern:

Be it known that I, MARTIN COWLES, of Unionville, in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in Ice-Picks; and I do hereby declare that the following isa full, clear, and exact description thereof,

whereby a person skilled in the art' can make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

Like letters in the figures indicate the same parts.

My invention relates to that class of tools which are used to break ofi"pieces of ice, and reduce them to a proper size for'consumption in theordinary manner.

The object of my invention is to provide a cheap tool made wholly ofmetal, of the proper size and weight of handle, Without resorting to theexpensive method of casting the handle hollow. I

In the accompanying drawing, Figure 1 is an exterior view of my improvedice-pick. Fig. 2 is a section through the middle of the same.

A is the blade, which is made of round steel, and sharpened in the usualmanner. The upper part, within the handle, is made taper, as

shown in the section, Fig. 2, and has upon the extreme end ascrew-thread to hold the top of the handle. B and 'C are the two partsof the handle. The lower part B has a hole at b cast in it, and reamedout to a proper size, so that it can be driven onto the taper part ofthe blade and remain fixed in its position.

The upper part C has a thread tapped into ahole in the top, and screwsonto the blade and rests on the lower part around the circumference nmlapping over an inside lip on B, to form a secure and tight joint. Thetwo parts B and C are cast in the ordinary manner in the form of cups.dle, which are useful when the tool is used as a hammer to break up icein the hand.

What I claim as my invention, and desire to secure by Letters Patent,is-- As a new article of manufacture, an ice-pick having-a hollowspheroidal-shaped handle, constructed of two parts, and having apolygonal zone formed thereon, whose angles form breaking-edges, saidhandle being attached to the pick, substantially as shown anddescribed.
